(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

Directions

1. Preheat the oven to 375°F (190°C) and grease a baking dish with olive oil.

2. Prepare the zucchini slices by salting them lightly and blotting with a paper towel to reduce excess moisture. This step is optional but recommended for better texture.

3. In a bowl, whisk together the eggs, milk or cream, garlic powder, onion powder, salt, and pepper until well combined.

4. Layer the zucchini slices evenly in the prepared baking dish. Pour the egg mixture over the zucchini, ensuring it’s evenly distributed.

5. Sprinkle the shredded cheese and grated Parmesan on top of the zucchini.

6. Optional: Add a topping of breadcrumbs or almond flour if desired for extra crunch.

7. Bake uncovered for 25–30 minutes, or until the casserole is golden on top and set in the middle.

8. Once baked, remove from the oven and allow it to cool slightly before garnishing with fresh herbs like parsley, thyme, or oregano.

9. Serve warm and enjoy!

Variations

• Different cheeses: Feel free to swap the cheese for any of your favorites. Gruyere, mozzarella, and cheddar work beautifully, but you could also try fontina, gouda, or even a mix of cheeses for added flavor.

• Herb options: Customize the flavor profile by experimenting with herbs like basil, thyme, rosemary, or dill. These add a fresh, aromatic touch to the dish.

• Low-carb toppings: If you’re following a low-carb diet, consider using almond flour or crushed gluten-free breadcrumbs instead of regular breadcrumbs for a crispy, crunchy topping.

• Vegan option: For a dairy-free or vegan version, you can replace the cheese with vegan cheese and use plant-based milk, such as almond or oat milk.

FAQs

1. Can I use frozen zucchini for this casserole?

While fresh zucchini is preferred for its texture, you can use frozen zucchini. However, be sure to thaw and drain the excess moisture before using it in the recipe.

2. Can I make this casserole ahead of time?

Yes, you can prepare the casserole the night before and refrigerate it. Just cover it tightly with plastic wrap or foil and bake it the next day.

3. Is this recipe gluten-free?

Yes, this recipe is naturally gluten-free if you skip the optional breadcrumbs or use a gluten-free alternative like almond flour.

4. Can I use heavy cream instead of milk?

Yes, heavy cream can be used for a richer and creamier texture, though it will make the dish higher in fat.

5. How can I make this casserole spicier?

If you like heat, try adding red pepper flakes or cayenne pepper to the egg mixture, or mix in some diced jalapeños for a spicy kick.

6. Can I freeze the casserole?

Yes, you can freeze the casserole before baking it. Wrap it tightly in plastic wrap and aluminum foil, and store it in the freezer for up to 3 months. Bake directly from frozen, increasing the cooking time by about 10-15 minutes.

7. What can I serve with this casserole?

This casserole pairs well with a light salad, roasted chicken, or a side of steamed vegetables. You can also serve it with some fresh crusty bread for a complete meal.

8. Can I make this casserole without eggs?

You can substitute eggs with a flax egg or chia egg (1 tablespoon ground flaxseed or chia seeds mixed with 3 tablespoons water per egg), although the texture may change slightly.

9. How do I get a crispier top on my casserole?

To get a golden, crispy top, broil the casserole for 1-2 minutes at the end of the baking process. Keep an eye on it to ensure it doesn’t burn.

10. Can I add other vegetables to this casserole?

Yes, you can add other vegetables like bell peppers, mushrooms, or spinach. Just make sure they’re chopped into small pieces and sautéed to release excess moisture before adding them to the casserole.
